' PLASTIC PRODUCT.

No Drawing.

To all whom it may concern Be it known that I, WALLACE APPLETON BEATTY,a citizen of the United States, re

siding at New York, in the county of New York and State of New York,have inventedv certain new and useful Improvements in 7 PlasticProducts; and I do hereby declare the following to be a 'full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to plastic products adaptedfor a wide variety ofuses, and has for its object to produce products of this nature whichwill be water-proof as well as insoluble in chemicals in general, andwill therefore, be more eflicient for many uses than thoseheretofore-proposed.

To these ends the invention consists in the novel products made from anovel gum,

all as will be more fullv hereinafter dis closed and particularlypointed out in the" claims.

In order that the invention may be more clearly understood, it is said:In my prior application #702,046, filed June 6, 1912, entitledArtificial gums and procem of producing thesame, I have disclosed andclaimed a new gum and method of. making it, which method, when brieflystated, consists in forming a new compound from a mixture of acetone andphenol to which is added a small quantity of acid, in order to producewhat I believe to be dioxy-diphenyl-dimethyl-methane. This new compoundis then further acted upon, as stated in said application above,byformaldehyde, in order to produce a further tenacious product constithattemperature for say .two hours, it isscarcely soluble at all even instrong alkali. When brought to this condition, however, acids willconvert it at ordinary temperatures into a mass which is insoluble inalkali.

Specification of Letters Patent.

Patented Nov. 2,1915.

' Application filed January 3, 1913. Serial No. 740,076.

I find the gum is also soluble in alcohol,

ether, acetone, glacial acetic acid, amyl alcohol, amyl acetate andacetylene tetra-chlorid, or mixtures of these. It is, however, insolublein oils, such as'linseed oil, turpentine, and mineral oils. When in itsinsoluble'condition, it is an inodorou'srtransparentmassquitestrong:mil-brittle and tenacious. It 1s a so quite hard andwill not burn unless kept continually in the flame. In this condition ofthe gum, I have not found any solvent for it.

Avariety of new products may. be made from this new gum as will now bedisclosed. For example, I have found thatit is sulficiently inexpensiveto manufacture to serve as a most eflicient tiling or floor covering.

For this purpose, I mayimpregnate blocks of wood of various sizes, orblocks of cement,

or other porous substances, with the new gum and form the floor materialthereof in the same manner that it is now formed of the regular productsin common use.

The gum likewise constitutes a most eflicient floor polish, and for thispurpose the wood itself may be simply impregnated with the gum in amanner similar to the impregnation of wood with ordinary varnishes.

The solution of the gum, of course, is

regulated to give the proper consistency for the partlcular purpose towhich it is applied.

' But, in some cases, I prefer to heat the coated substances to atemperature sufficient to render the gum insoluble in chemicals ingeneral, unless of course the said temperature, usually about 100 to.1500., will injure the "substances coated. As an alternative method ofmaking the coating absolutely insoluble, I may, when I make the solutionof the gum, add suflicient acid to give the said solution an acidreaction rather than an alkaline one, whereupon I have discovered thatthe gum upon drying, will itself become insoluble.

Another new product arises from the-use of my new gum in leathersdressed or coated with this said gum. In producing these products, theleather is prepared in the same 'way, or in a manner similar to thepreparation now employed when coating thesesaid leathers with the wellknown pyroxylin compounds; my gum in solution, preferably has ahighpolish. Of course, the leathers may be suitably colored in the wellknown manner, and I find the-gum itself takes dyes and other coloringmatter, so that the products may be given any desired color and finish.-Of course, the leathers may be finished by passing through rollers, orby other well kn Fabrics, suchas-cloth .papg, etc., may

likewise be coated with this gum,and in such cases, I prefer to have thecoat rather thin in order to produce the necessary fiexiblhty.

For some purposes, I prefer to impregnate the leather as well as thefabric with my gum, and thereby produce harder and more tenacioussubstances. In fact, I may impregnate paper with the. gum to produce a Ihard tenacious insoluble board material,

Which may be used as a roofing material, as lumber, and for a largevariety of uses.

I may further load the gum with various filling materials, such as sand,for example, when a roofing material is to be produced, or such asleather dust, wood dust, graphite, and a host of other substances, inorder to adapt the finished material to special uses.

A very pleasing and useful article is produced by'simply coatingpolished or stained Wood with this gum, wherein the same may be sawedand cut up as ordinary lumber to produce articles of furniture or otherarticles, or the furniture and other articles may be as made of ordinarywood and gum applied thereto. In this latter case, I have found thatwhen therarticle is exposed to the weather over long periods of time,the gum retains its high polish and brilliant effects unimpaired,whereas the best furniture varnish under the same conditions, goes allto pieces. 7

I have found it especially useful to subject wood to a baking or heatingprocess in order to render the same porous before applying the gum, inwhich case, the grain of the wood. is made permanent, which showsthrough the gum to render it very ornamental, while the said gum is thusafforded a firm and safe anchorage into the material of the wood.

The gum when dissolved and mixed with a suitable pigment, such forexample, as lamp black, zinc oxid, etc., makes a very hard tenacious anddurable enamel. The gum, whether heated or not, is found to be otlidisolvents according) is written.

in paper containers of all kinds which may be impregnated or coated withthis gum to render the same liquid tight, strong and durable.

Another use to which this gum is readily applied is for the productionof adhesives, cements, mucilage substitutes, etc. In such cases, it is,merely dissolved in the proper solvent, such as ether, alcohol oracetone, or to the purpose to which the cement is to e applied andpreserved in proper container, whereupon it may be applied directly tothe article and allowed to dry.

A further use for this gum is in the coating of statues, houses,structures of cement, of bricks, and other porous material in general,in order to render the same moisture proof. Even shingles and roofs ofhouses may be coated therewith.

It makes a good artificial ivory, horn, tortoise shell, etc., whensuitably colored and loaded with other substances, such as used inconnection with pyroxyline to make similar articles.

The gum further is found to be very useful in coating the walls ofrooms, bath rooms, etc., whereupon they have an enamel finish to whichwater may be applied and the room kept ina perfectly sanitary conditionat all times.

It further makes a good indelible ink in that when once applied to aporous surface, it cannot be gotten out without destroying the paper orother material upon which it For this purpose, it may be given anydesired color, and when linen is marked therewith,,it is impossible toget it out of the material short of the destruction of the fabric.

The gum is especially applicable ,to the manufacture of dress suitcases, trunks, and other such receptacles, for which purposes it may beeither used loaded with other ma-- In fact, the

and it may be modified in texture and appearance to suit the particularuse to which it is made.

When a sufiicient amount of solvent is added thereto, it may be made asliquid as water, and when a lesser amount of solvent ed, or otherwiseshaped to suit the then one has, in this gum, at his command a veryinexpensive material out of which he may readily mold articles capableof the,

widest variety of uses and which have a commercial importance.

When this gum is suitably colored, as by a variety of yellow anilindyes, or suitable pigments, a very good imitationof amber may beproduced.

When thegum is properly made, it is-very transparent, and therefore, itlends itself well to the production of imitation amber,

tortoise shell, ivory, etc.

There are a number of other uses to which my new gum may be applied,which are not necessary to mention, but one quite important use is thatof paints of the nature of bronzing liquids.

and pyroxyline can be greatly improved by I my product, by simplydissolving my gum in 'solutionof my gum, in order to render saidarticles less inflammable. In order to accomplish this, the saidarticles may be either dipped in the solution, or it may be otherwiseapplied thereto.

A, valuable use of adhesives or cements madefrom my product is found inthe anchof ing of brush bristles to their holders. For this purpose, thegum is dissolved to the proper consistency and the ends of the bristlesare coated therewith, there being sufficient ofthe material left tofirmly anchor the bristles to their holders.

Another most important usefor my product is the insulation of wires andconductors in general. For this purpose, a solution of the properconsistency is made up, and the said solution material applied to thewire in any suitable and well known manner; for example, as by passingthe wire through a bath containing the solution, or by impreg-' natingstrips of cloth with the solution and wrapping it around the wire, or bycovering For example, the well known so called aluminum paintconsisting.- of finely divided aluminum, amyl acetate,

the wirewith asuitable fabric or other material and impregnating thesaid fabric or material with my solution.

Of' course, slab like articles, or other.

shaped articles may be made out of my material andused likewise forinsulating purposes precisely as is hard rubber used at present.

A number of insulating uses are found, in my product when filled withsilex, lamp black, and other pigments. In such case, it resembles hardrubber, takes the place of'the for lamp sockets, etc. Another use for mygum is found in the making of matrices for use in connectionsame for alarge variety of uses, especially still more quickly. In the foregoingprocess,

I find it convenient to employ a filler such as powdered asbestos,silex, or other heat resisting material in the gum, and accordingly loadthe gum with one or more of such materials, in order that the finishedmatrix may effectually resist the molten metal to which it is subjected.

Not only may I employ acetone, phenol and aldehyde to produce my gum, asabove mentioned, but I may of course, use homologues of these andproduce similar sub stances, which would come well within the scope ofmy invention. A good homologue for acetone is di-ethyl ketone or ethylmethyl ketone, and cresol, as well as acct-aldehyde in place of phenoland formaldehyde respectively, all as will be obvious to those skilledin the art.

It is therefore obvious that those skilled in the art may vary theproperties as well as 1'.
